ELECTRIC CURLING-SIRON.

Specication of Letters Patent.

Patented Mar. 25, 1913.

Applica-tion led July 15, 1912. Serial No. 709,596.

T all whom it may concern:

Be it known that I, ACHILLES C. G0UGH, a citizen of the United States, residing at Pocatello, in the county of Bannock and State of Idaho, have invented Vcertain new and useful Improvements in Electric Curling- Irons; and I do herebyl declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This. invention relates to improvements in curling-irons, and particularly to what are known as electric curling-irons.

' The object in view is to provide new and improved meansv for curling or waving the hair in such manner that the hair when dressed with this appliance will have a curly or wavy appearance, more nearly approaching that of naturally curly 4or wavy hair.

.A further object of theinvention is to provide improved means for maintaining the working membersof a curling iron at the proper temperature, for curling or waving the hair, by the heating effect of an electric current.

Another object of the invention is to provide an improved heating element, to be contained within each working member of a curling-iron, the resistance of said element'or elements to be such that the emission will equal the inflow of energy at a predetermined temperature.

With these and other objects in view, the invention comprises certain novel principles, constructions, and arrangement ,of parts as will be hereinafter more fully described and claimed.

' In the accompanying drawings: Figure 1 is a vertical sectional view through an embodiment of the invention, certain parts being shown in elevation.` Fig. 2 is an enlarged view` of a heating element, partly in section at the ends, disclosing the construction of said heatin element. Fig. 3 isa cross section throng 1, approximately on line A-B. .IF ig. 4 1s a circuit diagram,A

showing a specific method of connecting the heating elements to the source of current Fig. 5 is a vertical view of the curling-iron disclosing the methodv of applying said iron to the hair for producing the effect of naturally wavy or curl .-hair.

Corresponding parts 1n all the figures are denoted by the same'reference characters.

In forming a device embodying the invention, the heating elements of the same may be connected through a suitablefcord and removable plug toa standard incandescent lamp circuit using either alternating or direct current.

In order that the invention may be more clearly understood, an embodiment of the same is shown in the accompanying drawings.

In the drawings, 1 and 2 are seamless steel tubes closed at one end and secured nearly parallel relatively to one another, by being brazed or welded to the steel cup, 12. The working members, liand 2, and the steel cup 12 are rigidly supported by a wood handle, 10. In order that any portion of hair, 26, should not have a tendency to slip ofi' the end .of one working member while being placed around the other working member, said working members, 1 and 2, mayV have the closed ends turned outwardly away from each other, as shown at 13 and 14. A

5 and 6 are very small 'metal rods covered, heavily, vwith lire-prooi' insulating material forming, respectively, the cores, 15 and 16. The resistance wires, 3 and 4, are supported, respectively, by the cores', 15 and 16, and the resistance wires mayor may not be covered withiire-proof insulating material, said resistance wires being electrically connected at the outer ends to the central -metal rods after the manner shown at 25, Fig. 2. Thus, one terminal of t-he flexible cord, 9, is divided into two parts, secured and electrically connected to the two central metal rds, 5 and 6, respec "tively, as shown, at 7 and 8; the other terminal of cord, 9, being secured and electrically connected to the resistance wires, 3 and 4, as shown, respectively, at 24 and 28, Fig. 4. The resistance wires may be electrically connected in series or. parallel. The circuit diagram, Fig. 4, shows parallel connection, the rods 5 and 6 being electricallyconnected to the resistance wires, 3 and 4, as shown, respectively, at 25 and 27, Fig. 4. Then, in the circuit diagram, Fig. 4, 9 represents a iiexible cord, 21 representsa removable plug and 29 represents a standard incandescent lamp socket; the electrical circuit being completed through 'the rods, 5 and 6, and the resistance wires, 3 and 4. The heating elements proper are further wrapped by wires ycovered with nre-proof insulating material, these binding wires are applied near the ends and near the middle of the heating element, as shown at 17, 18, 19, 20,' 22, and 23,' these Wires, 17, 18, ets., serve the duall purpose of binding the resistancewires, 3 and 4, more securely upon the cores 15l and 16, and that of retainingthe resistance elements in their proper positions within the steel tubes.

. What I claim is:

1. lIn a device of the character described,

the combination of a casing, heating elements seated therein, and means spacing saidheating elements from said casing cornprising Wire-Wrapped end and center Sectional bearings.

2. In a device yofy the character described,

the combination with a casing, of heating l devices having internal, metali1c-and elec- -tric' connecting elements, fire-proof insulation' insulating said elements, 'wire' heat-generating coils encircling saidinsulation and -connected to said internal, metallic, electric connecting elements at one end, and closely Wrapped, insulated wire supports at the`end and center portions of said heating devices,-

lto ,support said heating devices into spaced position to said casing.

In testimony vvhereof'l have aixed my. signaturein the presence'of two Witnesses.
